Extreme Weight Loss 2019: How Much Weight Can You Lose In A Week??

how much weight can you lose in a week without eating

Important note: Don’t follow the advice below if you are under 18. 

People always ask: How much weight can you lose in a week?” Well… to answer your question I have good news, awesome news, and bad news.

First onto the good news: YOU CAN LOSE A TON OF WEIGHT IN ONE WEEK

That’s right, you don’t have to be bound to the conventional wisdom of only losing 1 or 2 pounds a week. Extreme weight loss diets can definitely work, but only for a short period of time.

In fact, you can lose up to 15 pounds in one week if you do it correctly.

Now onto the awesome news: ALL THAT WEIGHT YOU LOSE WILL BE WATER AND FAT, NOT MUSCLE

Yup, you read that correctly, if you follow the methods at the end of this post, all the weight you lose during the week will be pure body fat. The conventional statement that losing more than 2 pounds per week leads to muscle, organ, and hair loss is absolute unicorn shit.

How do I know this? Because some awesome scientists from the American College Of Nutrition back in 1999, conducted a study, which tested 2 groups of people for 12 weeks.

One group only did traditional cardio, while the other group only did weight training. Both groups ate 800 calories a day. At the end of the study, both groups lost large amounts of weight, but the one that only did cardio lost large amounts of lean muscle mass, and the one that only did weight training didn’t lose any muscle mass at all.

So there you go, some hard hitting scientific facts that prove that you will not lose muscle during extreme dieting as long as you lift weights.

Note: And if you don’t have a gym membership or if you don’t have access to any weights, then doing a well-designed bodyweight program like Bodyweight Burn is your next best option.

And lastly, the bad news: YOU HAVE TO EAT VERY VERY LOW CALORIES

So yeah…. you have to eat a ridiculously low amount of calories to lose a lot of weight in a week. I’m talking along the lines of 800 calories a day. The amount that would make any nutritionist hang themselves.

And now, onto the plan, but first, a picture of steaks:

I didn’t want to put a boring picture of a scale, so here’s some delicious steaks. I’m guessing this isn’t the best article to put this picture in

The 2 step plan to lose the maximum amount of weight in a week

Please note that the following plan can be used by both men and woman.

And don’t do this plan if you’re under 18, you’re way too young to be eating such low calories.

I guarantee that if you follow the plan below, you will lose 10-15 pounds(water and fat) in one week:

1) For one week only, eat 800 calories per day.

2) Workout 2-3 times per week with weights. Make sure the weights are heavy and be sure to hit all body parts.

That’s all.

Some notes/tips about the above 2 steps:

  • 800 calories is very little food, for any man, woman, or baby walrus. Because of this, I suggest that you only eat 1 meal per day a la Brad Pilon’s Eat Stop Eat. If you eat one 800 calorie meal per day, then you’ll at least feel somewhat satisfied, but if you split that up into 3 or even worse, 6 meals per day, then you’re not going to fare so well on this one week venture. Yes, this means that you will be fasting 24 hours every day for a whole week. Just remember, you will be burning fat, not muscle.
  • Whenever possible, eat higher protein and eat foods with high water content such as fruits and soups. Also, drink lots of coffee and green tea, since they both tend to blunt hunger quite well.
  • Stick with heavy compound exercises when in the gym. That means no curling and crunching, and if you even step foot on a treadmill, my dumbass radar will go off and I may have to kill you.
  • Above all, keep yourself distracted and out of the kitchen. If you’re constantly prancing around the kitchen and thinking about food, you’re going to fail. So keep yourself busy. Read a book, play some video games, take a nap, work on your tan, or shave your pubes. I don’t care. Just do something that doesn’t involve food.
  • [EDIT 10/6/2014] I should also add that your protein intake needs to be HIGH. Like really high. In fact, the majority of your calories should probably come from protein, fruits, and veggies if you want this diet to be effective. The protein will help keep you full but more importantly also help maintain muscle.

Remember, this is only for one week

I just wanted remind you all, that this sort of extreme weight loss plan is only a temporary plan. The results don’t have to be temporary, but the plan is. Please do not try and do this weight loss plan for more than a week. Doing so is really going to mess with your head and you’ll most likely binge back to your original weight. After one week, transition to a more moderate weight loss plan for the long haul.

I hope you guys now know the answer to “How much weight can you lose in a week?”

Take it to the next level with the Xtreme Fat Loss Diet

Many people have been asking me, “Can I do this for more than 7 days?”

And the answer is no.

The way I laid out the diet above at 800 calories, you can’t do it for more than 7 days.

But there is a more strategic approach you can take where you can go and lose a ridiculous amount of fat in 25 days or less.

The program is called the Xtreme Fat Loss Diet, created by fat loss experts Dan Long and Shaun Hadsall. It’s essentially a much more fleshed out version of the plan I laid out above that will allow you to lose MASSIVE amounts of fat and get as lean as possible in just 25 days. Plus the program incorporates cheat meals so you still get to eat your favorite foods.

  1. I’m 18 years old, 220 pounds, and 5 ft 7. I don’t know how I got to this weight but it’s really bothering me. I want to get to a normal weight (unsure of what that is because different sites have different answers) or drop 80-100 pounds. I want to do it as quickly as possible but I don’t have regular access to a gym because I travel all the time. Any suggestions help.

  2. I’ve got 21 pounds to lose maximum so can I do this for one week take a break for say 3 weeks then do it again to lose it all? Sounds pretty extreme but I’m desperate to lose the weight! Also what time of day would you’re recommend eating? I get hangry when I don’t eat 3 meals aday? Thanks for any advice!

  3. Hi Keith, thank you for your inside advice. I am 61 years old, I weigh 73 kgs and want to return to my normal weight of 52kgs. I thought a week of nothing but fluids ie tea might help me kick start the weight loss process. Should I be doing cardio in this first week or not? In advance, thanks for your advice

  4. hello keith! I just found this while I was looking around making sure my new 800 calorie diet is safe. I started it several days ago, and I’m feeling very confident in my willpower and all that, however the problem I’m facing now is that I really want to start incorporating the kind of exercise you mentioned into my life, but I’m honestly not feeling that great. nothing alarming, but kind of weak, tired, etc. is it normal to feel this way and should I push through it and exercise anyway, or is it a bad sign that I’m not feeling good? I just don’t wanna accidentally push myself too hard, especially if it’s unusual to be feeling like this. thank you in advance for your advice!

    • just finish the 800 cals without exercise then move onto something MUCH more sustainable. I’ve said this 10000000000000 times, THIS IS NOT magic. It’s just to kick start the fat loss process a bit.

  5. Keith, why should you not do cardio? It seems counterintuitive to lift weights and not do cardio because muscle weighs more than fat. I need to lose at least 12 pounds by the 23rd (8 days) to win my Healthy Wage bet. I’ve been busting my butt doing cardio the past few weeks. Should I stop and just do weights to lose the most weight?
